Flake appeared Tuesday on CBS This Morning to talk about his new role, and confirmed he will not be a candidate in the 2020 presidential race. “I’ve always said that I do hope that there is a Republican who challenges the president in the primary. I still hope that somebody does, but that somebody won’t be me. I will not be a candidate,” Flake said.

Flake will contribute to a new series for CBS News titled Common Ground, a series of stories that the network says are meant to “shine a light on opposing groups coming together.”

“Common ground might be dead in Washington, but it’s alive and well everywhere else – on city councils, in state legislatures, any kind of association or group, people find common ground. It just often doesn’t translate into something in Washington,” Flake said.

“It was one of the rare examples where common ground found at the local level translated into action in Washington. There can be many more examples of that. And that’s what this series will look at, those areas of common ground around the country,” Flake said.

Flake left the Senate earlier this month. He was frequently an outspoken critic of President Donald Trump, and occasionally broke with Republicans on certain issues.
